Rules of
the game.

Each player starts with seven pieces. The highest triple starts and is played automatically.

Play one piece per turn. Numbers must match at every point where pieces touch.

Can't - or don't want to - play? Draw a piece into your rack. After the third draw, either play a piece or end your turn.

The plane expands without a boundary. New pieces connect to the open perimeter of the existing layout.

The sphere has 80 faces. Its edges and points wrap around the complete shape, so pieces can meet again from the opposite direction.

First to clear their rack wins. Others place in the order they clear their racks, or are ranked by points if they can't clear.

Score +2 per piece played, −1 per draw, and −2 per piece left at game end.

If a full round passes without a placement, the game ends and remaining players rank by score.
